Abstract: An autonomous vehicle detects an approaching emergency vehicle by performing a plurality of types of analysis of signals output by sensors in the vehicle. Each type of analysis generates a different prediction that indicates a likelihood of a proximity of an emergency vehicle to the autonomous vehicle. The predictions are processed and fused to generate a determination that indicates whether an emergency vehicle is proximate to the autonomous vehicle. In response to the determination indicating the emergency vehicle is proximate, the autonomous vehicle performs an action.

Abstract: A facsimile receiver having means for receiving signals and having writing means for writing on a copy medium on a rotatable drum 110, further includes a modulator means (130,159) for generating a signal transmission to a remotely located transmitter during predetermined intervals in which received signals are absent. The signal from the receiver provides a periodic handshake function. The duration of the signal is short compared with the duration of the predetermined intervals. The receiver is thus able to participate in handshake signalling without necessitating reduction of the bandwidth available for facsimile transmission.

Abstract: This invention relates to a railway wagon suspension unit of the type comprising a frame (1) mounted over a saddle (2) accommodating an axle journal housing (3) with a load spring suspension system (6) disposed between the frame and the saddle. The saddle bears on the housing through a mounting which includes a rubber block (17) together with the conventional rib (19) and channel (20) structure, the rubber permitting a controlled degree of movement between the saddle and the housing principally restricted to longitudinal motion in the direction of travel of the wagon, in which rubber yields to shear stress, and lateral motion by which the saddle pivots on the mounting about the housing. The principal advantage of the introduction of this mounting is that the axle is permitted to self steer into tight curves at low speed whilst retaining satisfactory high speed performance. Hitherto, the wedges have tended to accommodate longitudinal motion on curves only in a comparatively disjointed fashion by somewhat 'stepwise' slipping and this has been particularly marked at low speeds.

Abstract: A fixed spot transport vehicle which can be moved in front of a horizontal coke furnace battery to receive the incandescent coke on the coke side is equipped with a base which can be tilted towards a coke ramp. The rear wall of the transport vehicle, which faces the coke furnace battery, consists of a lower part (17) constructed as a single piece with the base wall and an upper part (18) which is suspended at its upper edge in swivel bearings (19) of the transport vehicle and whose lower edge loosely overlaps the upper edge of the lower part (17) on the inside so that the upper part (18) can be lifted into an approximately horizontal swivel position around its swivel bearings (19) for tipping. The transport vehicle is suitable, in particular, for those coke furnace batteries in which the distance between the base of the furnace chamber and the rails for the transport vehicle is small and the coke ramp is situated at a low point, and in which a discharge of the transport vehicle is designed to be possible during the journey under a fume hood which also travels to the quenching tower. The joints necessary for swivelling the movable parts of the transport vehicle are outside the region affected by the incandescent coke on the transport vehicle. <IMAGE>

Abstract: A device for transferring pieces, in particular metal keys, from an infeed station (25) to an operating and discharge station (26) has a turret (1) that comprises a tubular member able to rotate around an axis (A) perpendicular to the transfer plane of the keys (5), the upper part of which extends horizontally to form a support and guide element (20) for a movable carriage (13), provided with a clamping device (17) that withdraws a key (5) from an infeed station (25) and transfers itto an operating and discharge station (26). An operating system exerts an effect on the turret (1) and causes, first of all the rotation just of the support element (20) from the infeed station (25) to the operating station (26), with the carriage (13) in a position of maximum retraction and, subsequently, the maximum advancement of the carriage (13) up to the working position, and once this has been done, the operating system causes the carriage (13) to retract again and this discharges the machined key (5). To conclude, the operating system causes the support element (20) to rotate in the opposite direction up to the infeed station (25), thereby giving rise to a fresh cycle.
